TFYHG™ oxygen content analyzer for oxy-fuel combustion is an oxygen analyzer, also known as an oxygen concentration analyzer, mainly used for measuring the oxygen content of boiler flue gas. Flue gas oxygen content is one of the important monitoring parameters for boiler operation and an important indicator reflecting the perfection of combustion equipment and boiler operation. Its value is related to factors such as boiler structure, type and properties of fuel, boiler load, operating air distribution conditions, and equipment sealing conditions. The smaller the oxygen content, i.e., the smaller the excess air coefficient, the greater the increase in chemical incomplete combustion heat loss and mechanical incomplete combustion heat loss; the larger the oxygen content, i.e., the larger the excess air coefficient, the greater the amount of air supplied. Excess air causes a decrease in furnace temperature, which not only affects combustion but also carries away a large amount of heat and dust, increasing the calculated result of pollution emission concentration. At the same time, a large air volume also increases the exhaust gas power consumption. Controlling the flue gas oxygen content is of great significance to controlling the combustion process and achieving safe, efficient, and low-pollution emissions.
